general problems of the 2007 GMC Yukon

I was traveling on the freeway at about 70 mph coming from a supervision training class along with a CO-worker and the following sensor lights started appearing on my dashboard: traction control off, stabilitrak off. This has continued to happen on a regular basis. I have taken it to the gm service at least twice and private repair facilities numerous times and the situation continues. It is now 01-28-2014 and the situation continues and is getting worse. Alone with the above issues now the "reduce engine power" light comes on and the engine shuts down. It has become very dangerous to drive this vehicle and no repair facility, gm or otherwise, knows how to fix the problem. I have to drive so this vehicle is what I drive but, it is dangerous and gm needs to fix it or recall for this issue. I need answers quickly I fear this issue is dangerous for all concerned especially when this happens on a freeway!!.

The contact owns a 2007 GMC Yukon. The contact stated that the fuel cap would not seal properly, causing the service indicator warning light to illuminate. The dealer made three attempts to duplicate the failure but to no avail. The contact did not inform the manufacturer of the failure. The vehicle was at the dealer where the contact was awaiting further repairs. The VIN was available. The current mileage was 69,000 and the failure mileage was 24,000.

My name is mario moreno, I reside in tucson az, I own ad my wife and I drive a 2007 g m c Yukon slt, my concern is our Yukon seems to lunge at times, what I mean is, when we stop our s u v at stoplights, stop signs, or pulling into our garage the rpm raises to what I feel is an unsafe levle . Which requires us to apply the brakes in a manner for which I and my wife feel is excessive pressure being applied to the brakes. We have expressed our concerns to our local g m c dealership more than five times in a one year time frame. Their responce is we and our techs, can not duplacate the issue we have expressed! we both feel this is an unacetpable responce. I know that the system inolved is non mechcanicle system that opperates the gas peddle it opperates the the accelorator peddle by the use sensors and or sending units. Please advise. Im we are very concerned about oue familys saftey. Yours truly mario moreno p. S thank you for your consideration.

Low oil light flashes. Oil is low a quart to a quart and a half every thousand miles. The oil pressure light states there is no oil pressure and to shut off the engine. Recently brought it to the dealer and now the dealer states it may be an internal engine problem. No definitive diagnosis and it is very costly. This problem has been ongoing for years. . . .

Vehicle gets extremely low gas, 13 mpg on average. Burns oil . Need to add 2-3 quarts of oil between oil changes. Engine cooling fan stays on for extended periods while driving. All of which the dealership says is normal for the truck. They removed the driveshaft because of clunking at 25k mi. Reaction carrier replaced and transmission reconditioned at 36,663 mi after car stopped in the middle of the street. Car had to be towed in. At 62k miles engine light on and idles rough. Replaced throttle body. At 67k won't engage in reverse and makes klunking sound from reverse to drive. Replaced reverse housing, reaction shell, etc. At 75k had a reaction carrier failure, lost power brakes and lost power to the car. Almost was rear ended. Had to stop in middle of parking lot during christmas rush. Waited 5 min and restarted. Engine light stayed on, but was able to get to dealership. Was told that throttle body needs to be cleaned every 15k miles under service maintence. This was the first time I heard this! not really sure why it had to be cleaned, though, just had the throttle body replaced 13k miles ago. It seems that there are major flaws in the design of the engine. Obviously, the dealership has been putting band aids on my problem because they don't know how to fix. I have been very lucky that my family and children have not been in a major accident due to the major flaws in the engine designs. Every time I get my car fixed, the tech assures me that they have fixed the problem. I am really afraid to drive this car with so many close calls. The car is a hazard to drive!.
